Manuscript Summary: This manuscript consists of two parts, bound together for the first time during the 14th century in Einsiedeln and annotated by Heinrich von Ligerz. The first part (1-137), which contains three works by Priscian and one by Rufinus, was probably produced during the 9th/10th centuries in Switzerland or Germany. The second part (139-318) contains works by Isidore and is in part a palimpsest. It was written during the 8th/9th centuries in northern Italy or Switzerland, probably in the same scriptorium as Cod. Sang. 908. (ber)
